I was not feeling good last night so I am at home and getting some more rest. To response to your questions regarding to the underdrain in bioretention swales. 1) the underdrain is intent to collect the water then convey to the storm drain system, not disturbing the water for infiltration. One of the UIC criteria is using pipes to disturb water for infiltration. 2) All the water then enters the underdrain will be thru the bioretention soil which already provided treatment. UIC's concern is all the water has to be treated. Therefore, we should be OK the way of the design, not violating any UIC requirements.

Generally,the submittal material is acceptable with the exception of top soil. Bioretention soil—Approved as noted. Tree Tie—Approved as noted. Watering Bag—Approved. Recycled Lumber—Approved. Mycorrhizal—Approved. Wood Chip—Approved as noted. Tree Skate—Approved as noted. For the top soil type A mix, we originally have a 2 way 50/50 mix of compost of sandy loam soil in the spec. During the last review additional comments were added and thru a phone conversation with Hebe, additional revision was made by deleting the two way mix description. Upon the review by the landscape architect (HBB), they think the soil is fine with the sod but not adequate with the trees. Is it acceptable to add in some compost in the soil mix at the tree planting locations, which is about 11 of them?

The closure will span two working days and occur sometime between October 23`d and October 31St The plan for traffic control along NE 10th St will mirror the existing approved plan for the corner of NE l Oth St and Harrington Ave NE. The only change is the location of the type 3 barricade, which will act as a final warning of the single lane closure along NE 10th St. Northwest Cascade will shield the open excavation in the work zone along NE loth St to protect the traveling public. Temporary fencing will be used to surround the site and, if necessary, the roadway will be covered with steel sheets. Any traffic control implemented along NE 1 Oth St will comply with MUTCD standards to ensure the safety of our employees, residents along the project, and the traveling public. If there are any questions or concerns regarding this alteration to the traffic control plan, please feel free to contact me at 253-848-2371. Thanks, Jeff Collins Northwest Cascade, Inc.

We also agreed that after the one year maintenance and guarantee period, the plants will likely require water to survive—especially during hot dry spells. (We still water the maple trees on the Maple Valley Highway with the Water Buffalo after being planted 14 years ago). Surface Water had agreed to pay for this watering as well (after the 1 year maintenance and guarantee) and PPNR would coordinate with you if this service is required for plant survival PPNR would manage the contract. 1 ft Thanks Leslie .LCJ&C'4.

Zimmerman; Richard W Marshall Subject: RE: 90% Harrington Avenue Review - Landscape Maintenance Agreement with Community Services Department The Surface Water Utility will agree to the following with respect to the Harrington Avenue NE Green Connections Stormwater Retrofit Project Landscaping Maintenance: The Surface Water Utility will pay for only the needed pruning, weeding, watering, litter control, plant replacement within the bioretention facilities, installed trees and mowing of the grass planted area, created within the project improvement areas only, for the 1-year plant establishment and construction contract maintenance period, which normally would be required in the construction contract for the contractor to perform. The Surface Water Utility will determine if plant replacement within the bioretention facilities is needed during the 1-year maintenance period, in coordination with Community Services. The Surface Water Utility will pay to replace any trees installed as part of the project that die during the 1-year maintenance period. The Community Services Parks Planning and Natural Resource Division will include this work as a separate work item in their annual landscape contract, after the scope of work and contract cost for the Harrington Avenue NE Green Connection Stormwater Retrofit Project landscape maintenance work is approved by the Surface Water Utility. The Surface Water Utility will pay the invoices for the approved landscape maintenance scope of work and contract cost associated with the project during the 1-year period following the project construction. Upon completion of the 1-year plant establishment and maintenance period, the landscaping maintenance responsibility will turned over to the Community Services Department to budget for and perform the landscape maintenance to the level deemed appropriate by the Community Services Department. The Surface Water Utility will be responsible for the maintenance of the catch basin and storm pipes associated with the bioretention facilities and any problems with the ability for the bioretention facilities properly drain and function as designed. This is the approach for the maintenance of landscaping that has been agreed to between the Public Works Department and Community Services Department on past projects and will be the approach used for the Harrington Avenue Green Connection Stormwater Retrofit project.

Not sure what a "landscaped common area" definition might be. I could not find a reference that addresses specifically, planting strips in the ROW I. IRRIGATION REQUIREMENTS: 1. Irrigation and Automatic Controller: 3 a. A permanent built-in irrigation system with an automatic controller shall be installed, used, and maintained in working order in all landscaped areas of industrial, commercial, and multi-family development, and landscaped common areas in single family subdivisions. b. The irrigation system shall provide full water coverage of the planted areas as specified in the plan. c. The irrigation system maintenance program shall include scheduled procedures for winterization. 2. Exceptions for Drought Tolerant Plants: Landscape plans featuring one hundred percent (100%)drought-tolerant plants or landscaping already established without irrigation systems are exempt from installation of a permanent irrigation system, but drought tolerant proposals must provide supplemental moisture by means of a City-approved temporary irrigation system for a period not less than two (2) years. The Administrator shall have the option of conditioning the approval (i.e., requiring a screening fence, etc.). An inspection will be required one year after final inspection to ensure that the landscaping has become established. An inspection fee, paid at the time of permit application, will be required and the fee amount will be determined by the Administrator.

Flatley Cc: Hebe Bernardo; Kelly Beymer Subject: RE: 90% Harrington Avenue Review Hi Terry, Hebe is going to include irrigation (try to include) as part of the project base on a follow up conversation that I had with her after this e-mail. I believe irrigation is a code requirement. If not a code requirement, hand watering is not an option or even contracting the amount of water necessary to maintain green grass. Would you please provide the controller information, specs for the system (rainbird) and other pertinent information. I explained that to budget hand watering was too great of an expense particularly since a good portion of this area is turf. The Public Works Crews will maintain the filterra systems and the rain garden infra-structure. PP and NR would contract maintain the mowing and the landscaping and Parks and Golf would maintain the irrigation. All of this will have to be budgeted for maintenance as part of the 15/16 budget.

I am not going to provide irrigation system costs or specifications as Hebe indicates no funding. I have no best method to estimate the cost for hand watering this material but would guess a budget of$20,000 per year would be close; we would have a better idea in year 2 of costs. There are no alternative methods for watering other than temporary irrigation, but again, no funding. How can hand watering be supported if no funding?

We (Parks Planning and Natural Resources) had previously agreed to remove unhealthy flowering cherry trees at the south end of this project which were to be replaced with new trees as part of this project. I could not find this identified on the plan set. Terry F. has the tree removals scheduled for this year. 5. 1 am unclear as to why some trees will remain with tree protection even though they are in such close proximity to the work area while others will be removed. Would you please clarify? 6. 1 am somewhat concerned about the location/orientation of some of the curb cuts. Many will require a person in a wheel chair to enter into the traveled ROW (particularly at the intersection of Harrington Ave. NE and NE 10th Street) . I have heard this comment/concern repeatedly from one of our former trails committee members who was confined to a wheel chair. Perhaps there are property constraints, however I would appreciate another review of these curb cut areas. 7. It appears no cross walk striping is proposed at the intersection of Harrington Ave NE and Glennwood Ave NE— however new curb cuts are proposed. Thank you again for the opportunity to review and comment. Please let me know if you have any questions. Leslie z"4e,.

I would add to your list below with the following: 1. Add Structure 6-6 to Issue No. 6 2. Add new issue: Contactor to provide as-built elevations to verify structure 4-3 and 4-5 rims were set at correct elevation. City believes the structures are set too high as the top slab extends above the bottom of the swale by about 10"-12". As a result, the overflow appears to be higher than the gutter which would allow storm runoff from the swale to discharge into the street instead of the storm system. If the rim is too high, the solution would be to remove the top slab and replace the 2' riser section with a 1' riser section. Another option would be to remove the 2' riser section, place the top slab directly on the base section and adjust the rim to the proper elevation using adjustment rings. 3. Add new issue: City and contractor will review as-built drawings to determine if drain basin rim elevations were constructed per plan. If not, the contractor will need to take corrective action such that drain basin rim elevation match the design plans. 4. Add new issue: The cobbles were not placed along the bottom the swale as shown on the plans. City Maintenance Manager will be evaluated whether additional cobbles should be added to match plans.

If there is anything else that needs to be added to the list, please notify me. 1 1. NWC is to install the orifices in the 9 catch basins coming from the bioswales. 2. The curb&gutter to the south of 1416 Harrington is cracked. NWC will need to remove and replace it. The City of Renton will a►low NWC to remove only the concrete curb &gutter and not cut/patch back the asphalt roadway. 3. The curb &gutter in front of the ADA ramp on the south side of the intersection of Harrington Ave NE and Index Ave is cracked. The City of Renton will allow NWC to remove only the concrete curb & gutter and not cut/patch back the asphalt roadway. NWC will need to remove and replace it. 4. NWC is to install the remaining 4 solid lids on the existing catch basins. 5. The City of Renton will look into what they would like for the castings/frames in the bioswales. The City discussed placing concrete collars around the castings/frames. The City of Renton will determine what they want done. 6. The City of Renton will decide what they would like done with the frame &grates installed at the intersection of Harrington Ave NE and NE 121h St. Apparently, NWC installed the existing frame &grates on the new type 1 catch basins. NWC can offer a credit for the frame &grates not installed, or remove and replace the frame & grates. Please hit "reply all" to this email so that Robert and Mike are included in this correspondence.

Puyallup, WA 98373 RE: CLAIM FOR COMPENSATION FOR GRAVEL BORROW FOR THE SUNSET COMMUNITY LID RETROFIT STORMWATER GREEN CONNECTION PROJECT, CAG-14-079 Dear Mr. Collins: The City has reviewed your claim for compensation for gravel borrow as outlined in your Action Request Letter dated December 8, 2014. The City's response is as follows: The payment of gravel borrow shall be paid by the cubic yard as defined in the 2014 WSDOT Standard Specification, Section 2-09.4. Section 2-09.4 clearly states that gravel backfill will be measured by the cubic yard in place determined by the neat lines required by the plans. Section 2-09.4 also states that the Contracting Agency will measure and pay for only the material excavated from inside the limits defined in Section 2-09.4. If the Contractor excavates outside these limits or performs extra excavation as described in Section 2-09.4, it shall be considered for the Contractor's benefit (saved cost on not providing shoring) and shall be included in the cost for other bid items. The attached spreadsheet shows the calculated gravel borrow quantity between the main line storm structures and lateral storm line structures, which are based on plan profile elevations and lengths of pipe. The horizontal pay limit (trench width) of the trench is determined from Standard Plan 220.00 in the bid document which references the WSDOT specification for trench width. For 12" diameter pipe, the excavated quantity shall be based on a trench width of I.D. plus 30" or 3.5'. For 18" diameter pipe, the excavated quantity shall be based on a trench width of(I.D. x 1.5) + 18" or 3.75'. The calculated volume of backfill is determined from the trench cross-sectional area within the pay limits multiplied by the trench length minus the volume of the pipe, bedding, crushed rock and HMA. Therefore,the neat line calculated quantity of gravel borrow is equal to 435.44 CY assuming 45% re-use of native. Assuming 100%gravel borrow, the neat line calculated quantity would be 791.67 CY. The bid quantity assumed 55% borrow plus 1.2%for a total of 523 CY. Renton City Hall • 1055 South Grady Way• Renton,Washington 98057 • rentonwa.gov Mr.Collins Page 2 of 4 January 27,2015 As of November, 2014, Northwest Cascade (NWC) has brought in 3,255 tons of gravel borrow (based on truck tickets), which equates to approximately 2,325 CY of compacted gravel borrow (assuming 1.4 tons per CY), which is almost 4.5 times the theoretical quantity of 523 CY. Even if we assume 100% backfill and add 20%, the revised theoretical gravel borrow would only be 950 CY (791*1.2), or 1,375 CY less than the truck tickets. NWC has exceeded the pay limits by a significant amount. The attached photos that show the excavated trench between NE 16th Street and NE 12th Street were taken in September when the 12" storm line was being installed. The photos show the trench patch along Harrington Avenue as well as the open trench. The photo with the tape measure shows the trench cold patch width at the top to be 9' across extending all the way down Harrington Avenue NE. The open trench photo gives a perspective of the trench cross-section and depth. Using the 12" storm pipe shown in the photo for scale, the lower portion of the trench is around 3.5' wide, which is consistent with the pay limits. However, at about 3' from the bottom of the trench, the trench widens to around 7.5' and maintains this width to the top of the trench. This Tee-cut or "bench" excavation exceeds the pay limits per Section 2-09.4 of the 2014 WSDOT Standard Specification and associated backfill beyond the pay limits is for the Contractor's benefit and; therefore, expense. The action request letter raised several issues for which a point by point response is provided below. 1. AR 13A, Paragraph 1, states that there were several utility crossings that prevented NWC from using shoring and that benching the trench was necessary. City Response: It has been my experience that shoring with trench boxes and steel plates can be used under most circumstances where there are utilities. I have managed several construction contracts where the contractor installed storm pipe through a dense corridor of utility crossings in downtown Renton. Because of traffic considerations, the contractor could not bench the excavation but instead used a combination of shoring boxes of different sizes and configurations as well as steel plates to maintain the trench excavation within the pay limits. As with any urban neighborhood, Harrington Avenue NE has the usual utility crossings of gas, power and water. However, compared to other areas of the City, particularly, the downtown core, the density of utilities is relatively low. The City's position is that the number of utilities within the project footprint is not unusual for a residential neighborhood and should have been factored into NWC's bid. 2. AR 13A, Paragraph 2, states that the trench excavation limits were within the City's allowable pay limits. H:\File Sys\SWP-Surface Water Projects\SWP-27-Surface Water Projects(CIP)\27-3635 Sunset Community Plan SSIP\1600 Construction\1605 Pay Estimates\Change Orders\Action Request 3 Gravel Borrow Compensation.doc\AQtp Mr.Collins Page 3 of 4 January 27,2015 City Response: As explained above, this statement is incorrect. The excavation exceeded the pay limits specified in the 2014 WSDOT Standards and Specifications Section 2-09.4. 3. AR 13A, Paragraph 3 states that many of the existing pipes had to be chased and relocated. City Response: The only pipes that were relocated were five side sewers. Since these relocations resulted in a change conditions (in conflict with storm), the City agrees to compensate NWC for any gravel import used at these locations since they would be in access of the trench pay limits for the mainline and lateral storm lines installed. 4. AR 13A, Paragraph 3 states that numerous utilities did not cross the new pipe at perpendicular angles. City Response: I counted three utilities on the plans that cross the trench at an angle greater than 10 degrees. In any case, this number is typical for any construction project of this type and should have been factored into NWC's bid. It is the City's position that shoring could have been used to shore the trench and benching was not necessary. 5. AR 13A, Paragraph 4 states that some utility crossings were not shown on the plans. City Response: There was only one side sewer that was not shown on the plans and was relocated. Please provide specific locations and types of utilities that were not shown on the plans and impacted your excavation. 6. AR 13A, Paragraph 5 states that the bid quantity of 540 CY (based on the neat line calculations) is not accurate because the truck tickets total more than 2,325 CY. City Response: NWC decision to bench the excavation resulted in a significant increase in excavated material beyond what would have been removed had shoring been deployed. Based on field observations, benching increased the width of the trench from 3.5' to 8'. Eight foot (8') was determined to be the average measured width based on averaging the measured width of the saw cut line (9') shown in the photo with the tape and the estimated bench width of 7' shown in the photo with the open trench. The bench width would therefore, be approximately 4.5', which is equal to the average trench width of 8' minus the neat line width of 3.5'. Using the photo showing the open trench as a guide, the bench height is approximately 3.5'. The 12" storm pipe shown in the photo is useful for providing scale. H:\File Sys\SWP-Surface Water Projects\SWP-27-Surface Water Projects(CIP)\27-3635 Sunset Community Plan SSIP\1600 Construction\1605 Pay Estimates\Change Orders\Action Request 3 Gravel Borrow Compensation.doc\AQtp Mr.Collins Page 4 of 4 January 27,2015 The cross-sectional area of the bench would therefore be approximately 15.75 SF (3.5' x 4.5'). See attached sketch showing bench dimensions. Based on a total of 1,981 LF of 12" and 18" diameter storm pipe installed, excluding the 53'of 18" pipe installed in the abandoned storm conduit at the intersection of Harrington Avenue NE and NE 12th Street, the total volume of excavation beyond the pay limits is approximately 31,200 CF or 1,155 CY. Adding 1,155 CY to the neat line calculation of 540 CY yields a total quantity of trench backfill equal to 1,695 CY. Assuming 100% gravel borrow, the total quantity of backfill would be 1,946 CY (791 CY+ 1,155 CY). Although still less than the 2,325 CY represented by the truck tickets, this extra quantity of backfill as a result of excavating beyond the pay limits specified in the contract documents significantly increased in the total backfill used in the trench and should not be paid by the City. NWC could have used shoring for the project but at its discretion, chose to bench the excavation. Again, as stated in Section 2-09.4: If the Contractor excavates outside these limits or performs extra excavation as described in Section 2-09.4, it shall be considered for the Contractor's benefit and shall be included in the cost for other bid items. The contract has a bid item for shoring. To date, the City has paid for 15,839 SF of shoring on the project. If NWC does not agree with the City's neat line calculations for gravel backfill, then NWC shall provide the City its own calculations, which justifies its claim for additional compensation for gravel borrow. Regardless, the City will only pay for Bid Item A-18 quantities based on neat line calculation as specified in Section 2-09.4 of the WSDOT Standard Specifications.

New development projects are required to construct frontage improvements including new sidewalks. City Transportation projects also require the construction of new sidewalks. The construction of sidewalks adds to the overall project's requirement for flow control mitigation and the need for flow control facilities and conveyance systems. These stormwater drainage facilities have construction, maintenance and replacement costs, and require land for construction. For linear transportation projects, flow control facilities require additional land, easements, or right-of-way due to the lack of space in most existing right-of-way. The use of porous concrete sidewalks allows the sidewalk to be modeled as 50% grass and 50% impervious instead of 100% impervious, potentially reducing the need for or size of a flow control facility or conveyance systems, which reduces costs. The use of porous concrete sidewalks is a way of reducing runoff from new construction, which reduces the need for conventional stormwater infrastructure, reduces downstream flooding, recharges aquifers that maintains base flows in streams, and improves water quality and fish habitat. As specified by the 2007-2013 NPDES Permit, the City's drainage code requires the implementation of flow control Best Management Practices (BMPs) for a portion of the site being developed. Porous concrete sidewalks are an option that is available for use as a flow control BMP. The adopted Surface Water Design Manual requires an adjustment if the porous concrete sidewalk is proposed to be placed in the City right-of-way by a private development. Mr.Zimmerman Page 2 of 9 January 22,2014 There have been two City projects where porous concrete sidewalks have already been constructed. These projects are the NE 3rd/4ti, Corridor Transportation Improvement project and the Lake Washington Blvd Storm and Water System Improvement (Hawks Landing) project. The Surface Water Utility is currently working on two Washington State Department of Ecology (Ecology) grant funded projects to install pervious concrete sidewalks on Harrington Ave NE (Harrington Ave NE Green Connections project). These projects were part of the Sunset Area Planned Action EIS that was approved by Council. The City was successful in obtaining the Ecology grant funds because the projects retrofitted stormwater runoff from the street to provide water quality and reduce runoff by the use of porous concrete sidewalks. In addition, the Renton Housing Authority (RHA) has been approved to install pervious concrete sidewalks as part of the Kirkland Townhomes project, but they are responsible for the maintenance of the sidewalk. The development and engineering community is interested in using pervious concrete sidewalks and pavements on future projects to reduce the storm water runoff impacts from their projects. This allows them to reduce conventional stormwater facilities for control of runoff and the associated cost. By reducing the space needed for flow control and water quality treatment facilities, it allows new development to create more buildable areas on their property. This results in increased property value, which is a benefit to the developer, but also to the City through increased property tax revenues. The new 2014-2017 Phase II NPDES Permit requires jurisdictions to adopt the Ecology 2012 Stormwater Management Manual for Western Washington by no later than December 31, 2016. The Ecology 2012 Manual requires new on-site stormwater management requirements. There are specific requirements for BMPs implementation of all hard surfaces. Per Minimum Requirement#5 on Pages 2-30 and 2-31 of the attached pages from the Ecology Stormwater Management Manual for Western Washington (Ecology Manual), all hard surfaces in projects resulting in more than 2,000 square feet of new plus replaced hard surfaces have to be mitigated (when feasible) by full dispersion, permeable pavement, bioretention, and/or sheetflow dispersion in the order listed, with the specific requirement of permeable pavement to be used when pavement is proposed. The applicant/engineer will need to demonstrate that a certain on-site stormwater BMP is not feasible in order to move down the list of on-site BMP implementation. The Ecology Manual provides feasibility criteria for all on-site BMPs including permeable pavements (BMP T5.15) on Page 5-16 attached for Permeable Pavement (porous concrete) feasibility criteria. An alternative for compliance with the on-site stormwater management requirement is to construct a facility designed per the Low Impact Development Performance Standard. See attached Page 2-30 for the Low Impact Development Performance Standard. Because stormwater mitigation in City right-of-way is space limited and may require land acquisition, the use of porous concrete sidewalk may be (when feasible) the best alternative for BMP implementation on right-of-way projects due to the lack of space for the facility and the cost for land acquisition.

Lower construction costs. Projects that use pervious concrete may not need to install catch basins, conveyance, and retention facilities. Grading requirements may also be reduced because there is no need to install conveyance systems and/or detention facilities. 2. Eliminates utility conflicts that may have been caused by conveyance installation. 3. Eliminates maintenance and replacement cost of all otherwise required catch basins, pipes and detention system. 4. Increases land utilizations. Since a pervious concrete surface doubles as a stormwater management system, there is no need to purchase additional land for installing large detention ponds and other detention systems. Therefore, the City, developers, and property owners can use land more efficiently and maximize the return on their investment. 5. Provides sidewalks in accordance with the City's Complete Street Standards while providing stormwater mitigation. 6. Channels more water to tree roots and landscaping, so there is less need for irrigation. 7. Directly recharges groundwater to maintain aquifer levels. Concerns with the Implementation of Porous Concrete Sidewalks: 1. Salt, sand, and other deicing materials may damage the surface during winter time. 2. Sensitivity to clogging. 3. Requires effective maintenance and cleaning to ensure sufficient capacity. 4. Life cycle cost of porous concrete is unknown. 5. Additional maintenance equipment and personnel needed. 6. Strength and durability of the pavement is unknown. 7. Compliance with ADA standards is unknown. 8. Issues regarding aesthetics., Doe- .4 t ►vuA—,A 9. Installation concerns. 10. Specialized staff training. The concern about the maintenance of porous concrete sidewalks centers around the experiences other jurisdictions have with moss growing on the sidewalks, increased maintenance requirements, pedestrian safety, sidewalk aesthetics, and public acceptance. There is no disputing that if not designed and constructed properly, or properly protected and maintained, moss could grow on porous concrete sidewalks due to the reduction of the infiltration rate or plugging of the void space in the porous concrete. Moss growth is more of an issue in shady areas. Moss can grow on conventional impermeable sidewalks and porous concrete sidewalks in the Pacific Northwest. The attached CH2MHill Technical Memorandum - Design and Installation Considerations for Pervious Concrete Sidewalk describes the design, installation, and H:\File Sys\SWA-Surface Water Section Administration\SWA 03-Correspondence-General\Maintenance\Porous Concrete Sidewalk\PCS memo_to_greg.doc\HCBtp Mr.Zimmerman Page 4 of 9 January 22,2014 maintenance considerations that, if followed, would minimize the potential for moss growth. These items include: • Infiltration testing of porous concrete/pavement. • Provide free draining pavement depth below soil frost layer. • Sufficient depth of level storage bed over uncompacted subgrade. • Positive stormwater overflow paths from infiltration beds. • Minimize runoff from adjacent pervious areas, adjacent areas must be stabilized (no erosion). • Type of native soil that is being infiltrated (A&B soil types best, C&D soil types may require an underdrain). • Location of groundwater table. • Steepness of slope (needs to be less the 10%). • Porosity of the concrete material (more sand, less porosity = more moss). • Construction and installation considerations: 1. Erosion control more critical. 2. Protection of native soil and base course required to maintain infiltration capacity. 3. More precise batching and more skilled installation required. 4. Must verify contractor qualifications and training. 5. More testing and inspection required during construction. 6. Special techniques required for placement, finishing, and curing. Porous Concrete Maintenance Requirements: The Washington State Department of Ecology develop )Of cific maintenance requirements/guidelines to ensure continue performa porous concrete. Those requirements are listed in the Ecology 2012 Manual on Page 5-22 (attached). Ecology recommends that permeable surfaces be maintained once or twice annually to maintain infiltration capacity using suction, sweeping with suction, high pressure wash and suction, or hand held pressure washing of void spaces for sidewalks. Porous Concrete Maintenance Programs: The most frequently cited concerns with the implementation of porous concrete is moss growth and surface clogging caused by organic matter and sediment that effects the functionality of porous concrete. The city of Olympia developed a maintenance program to ensure that porous concrete continues to function for its serviceable life. Four maintenance methods were analyzed including pressure washing, sidewalk sweepers, hard surface cleaners, and leaf/litter vacuum cleaners. Trial reports for each method were developed. The following table summarizes the results of the tests of the four maintenance methods. H:\File Sys\SWA-Surface Water Section Administration\SWA 03-Correspondence-Genera l\Maintenance\Porous Concrete Sidewalk\PCS memo_to_greg.doc\HCBtp Mr.Zimmerman Page 5 of 9 January 22,2014 Porous Concrete Description and Observations Sidewalk Maintenance method Pressure Washer Worked extremely well. All surface debris was removed. The best attachment for loosening and removal of debris was the power head cone nozzle. It is unknown how much of the material was forced deeper into the pervious material. Sidewalk Sweepers A Tennant 6400 sweeper, a PowerBoss® Badger SW/6XV sweeper, and a Green Machine 525HS sweeper were used. The Tennant and PowerBoss® machines use a vacuum system that applies a vacuum to the brush area for dust control. The Tennant and PowerBoss® did a fair job of removing material. Neither machine cleaned deep into the concrete pores. Operations are quick. Two passes were required to clean entire sidewalk width. The Green Machine did not do a very good job and was unable to pick up material. To be effective the sweeper needs to have a horizontal broom. Faster than pressure washing but does not clean as well as pressure washing. Hard Surface Cleaner Performed by Belarde Company, Seattle. A Prochems rotary spray jet (sprays a rotating jet of hot water under high pressure at the surface of the sidewalk while a vacuum retrieves the water and debris) was used. The system did a very good job of cleaning the porous concrete sidewalk, far superior to pressure washing alone. Production rate is equal to pressure washing method. Equipment needed to do cleaning is large. Leaf/Litter Vacuum Minuteman Parker Vac-35 (applies vacuum directly to the surface to Machine be cleaned). Machine works at a walking pace. Machine did a great job removing loose debris on the sidewalks surface and removing debris in the voids. Machine works quickly and is more effective than the leaf/litter vacuum systems. Should probably include a pressure washing component in the program to restore porosity if debris migrates lower than the level the vacuum machine can remove the material. From the analysis performed by the city of Olympia, the best method for maintenance in order of performance is: pressure washing, hard surface cleaner, leaf/litter vacuum machine, and the sidewalk sweepers. H:\File Sys\SWA-Surface Water Section Administration\SWA 03-Correspondence-General\Maintenance\Porous Concrete Sidewalk\PCS memo_to_greg.doc\HCBtp Mr.Zimmerman Page 6 of 9 January 22,2014 Cost for Construction and Maintenance of Regular Concrete with Required Stormwater Facilities vs. Porous Concrete: In 2005,the city of Olympia analyzed the difference between the maintenance cost of regular concrete vs. the maintenance cost of porous concrete sidewalks (see attached Traditional vs. Pervious Concrete Sidewalks Construction Maintenance Cost memorandum) using two methods: sweeping and pressure washing. The analysis was based on a total of 51,000 square yards of sidewalk to be constructed in a period of seven years. The maintenance cost for traditional sidewalk (including maintenance of a pond for required flow control mitigation) and the porous concrete sidewalks are listed below. Construction Cost Maintenance Cost Traditional Concrete $5,003,030 $155,610 Sidewalk with Pond Construction for Stormwater Mitigation Porous Concrete Sidewalk $2,615,359 $147,129 (for the more expensive pressure sweeping method) The city of Olympia's Porous Concrete Cleaning program includes vacuum cleaning once or twice per year depending on leaf litter from adjacent trees and is estimated to cost $0.10 per square yard. Pressure washing is done once every five to ten years and is expected to cost $1.60 per square yard of porous concrete. We would need to perform additional analysis to determine the maintenance cost for porous concrete sidewalks, if the city of Renton were to implement a maintenance program. Other jurisdictions allowing the use of porous concrete sidewalks: Pervious concrete sidewalks and pavements are being used in many jurisdictions in the United States and in other Countries. In Washington State, as the result of the Ecology NPDES Permits, it is being required with new developments and those requirements are increasing with the new 2014 NPDES Permit that has been issued by Ecology. King County has allowed new private development projects to install pervious concrete sidewalks, but requires a road variance to be approved by their Roads Department. King County currently assumes maintenance of the porous concrete sidewalks located in the right-of-way, but is considering making the property owner responsible for their maintenance with the future update of their Surface Water Design Manual. Also, King County has installed pervious concrete sidewalks and pavements as part of their Transportation and Transit CIP projects. King County's position is that the property owners are responsible for the sidewalk maintenance per King County Code, which is the same as Renton Municipal Code. However, they do maintain the pervious concrete sidewalk that they have constructed as county projects. H:\File Sys\SWA-Surface Water Section Administration\SWA 03-Correspondence-General\Maintenance\Porous Concrete Sidewalk\PCS memo_to_greg.doc\HCBtp Mr.Zimmerman Page 7 of 9 January 22,2014 The city of Seattle allows the use of permeable pavement but it is limited to non-street surfaces, such as sidewalks and planting strips only in public right-of-way. Seattle Department of Transportation (SDOT) will accept maintenance of permeable pavement in the right-of-way per Chapter 6.4.6b of the SDOT adopted Right-of-Way Improvement Manual (http://www.seattle.gov/transportationjrowmanualLmanuaII6 4.as #646). SDOT requires that a minimum area of 2,000 square feet or one block of frontage of permeable pavement to be constructed prior to accepting maintenance per SDOT Client Assistance Memo CAM 2215. The city of Olympia allows private development to construct porous concrete sidewalks in public right-of-way. If the porous concrete sidewalk is constructed in a common walkway area (abutting property is public property), or if it is constructed as part of a city project, then the City's Public Works Water Resource Storm and Surface Water Utility maintains the porous concrete sidewalks and the funding for the maintenance cost is programmed in the Surface Water Utility rates. When porous concrete sidewalks are constructed as part of a development project, they require the adjacent property owner to maintain the sidewalk per their City Code. They have seen problems with moss growth in shady areas and find that cleaning course aggregate porous concrete sidewalks is more difficult. The city of Olympia has also constructed several Transportation Improvement Projects and Stormwater LID projects listed at: http://olvmpiawa.gov/city-utilities/storm-and-surface- water science-and-innovations science-and-innovations- orous- avement. The city of Olympia currently performs maintenance (pressure washing) of the porous concrete sidewalks using part-time seasonal workers and the program costs approximately$10,000 per year. They have found that the finer grade of porous concrete is easier to maintain, since moss cannot grow from deep inside the porous concrete section and has a smoother surface that is easier to clean. They have also found that spraying the porous concrete with Scotts Roundup® controls moss, but they do not use it for environmental reasons and concerns from the public. There are more environmentally friendly sprays that could also be used, such as oregano oil, but there is still the public perception problem with spraying in their community. The city of Puyallup allows porous concrete sidewalks in their right-of-way and currently has two private development projects with porous concrete sidewalks with two other projects in the permit review process. Puyallup City Code requires the abutting property owner to maintain the sidewalks, standard or porous, in the city. However, they also do not have a history of requiring property owners to repair sidewalks at their own expense. They have not had any problems with moss growth on the porous concrete sidewalks, but they are relatively new sidewalks. The city of Puyallup has completed a project that included both pervious concrete and permeable paver sidewalks (8th Ave NW LID Retrofit project). The abutting property owner is responsible for the sidewalk maintenance, even though it was constructed as part of a city project. The city of Puyallup has recently paved two streets with porous asphalt and will be constructing at least two other projects with pervious concrete sidewalks, as well as porous pavement travel lanes. H:\File Sys\SWA-Surface Water Section Administration\SWA 03-Correspondence-Genera l\Maintenance\Porous Concrete Sidewalk\PCS memo_to_greg.doc\HCBtp Mr.Zimmerman Page 8 of 9 January 22,2014 Maintenance Responsibility: As with other types of street improvements, adjacent property owners are responsible for maintaining sidewalks, driveways and parking pads as well as landscaping in the street right-of-way, per our City Code. We can determine that the adjacent property owner is also responsible for the maintenance of porous concrete sidewalks, as currently required by City Code. To permit the placement of porous concrete sidewalks in the right-of-way, the City's Drainage Code requires a code modification similar to the King County road variance requirement. The property owners maintenance of the porous concrete sidewalk can be made a condition of the code modification and recorded in a covenant against the property. This is similar to how we allowed the Renton Housing Authority to construct porous concrete sidewalks in City right-of-way as part of the Kirkland Townhomes project. This would be consistent with our City Code requirements for impermeable sidewalks and with what other jurisdictions are doing. For City projects that use porous concrete sidewalks or use permeable pavements, the Department/Division/Section that constructs the project could be responsible for funding the maintenance of the porous concrete sidewalk or permeable pavement, but the maintenance could be performed by a designated City section. Another option would be for the City to accept the maintenance of the porous concrete sidewalks that are constructed in the public right-of-way and assign the maintenance of the porous concrete sidewalks to the Surface Water Utility and the cost for the maintenance program funded by the Surface Water Utility rates. The work could be done with in-house resources or contracted out to the private sector. This option would require the establishment of a budget that would need Council approval and require a Utility rate increase. Conclusion: The construction of porous concrete sidewalks in City right-of-way currently has mostly been done or is being proposed to be done as part of City projects, except the Renton Housing Authority Kirkland Townhomes project. The City will face increasing requests to allow its use and the use of permeable pavements for roadways in the future by developers and their engineers due to the benefits in reducing costs and the desire to build "green" projects that the public supports. The new 2014-2019 NPDES Permit will require the City to adopt standards that require more use of porous concrete sidewalks and permeable pavements after December 31, 2016. The most important method for avoiding the growth of moss on porous concrete sidewalks is following the design, construction, and maintenance requirements to establish and maintain the porosity of the porous concrete sidewalks to be free draining. H:\File Sys\SWA-Surface Water Section Administration\SWA 03-Correspondence-General\Maintenance\Porous Concrete Sidewalk\PCS memo_to_greg.doc\HCBtp Mr.Zimmerman Page 9 of 9 January 22,2014 Use of more sand in the concrete mix would result in less porosity, which may create conditions that are more conducive to moss growth. There are many examples of porous concrete sidewalks with moss growth, but this may be the result of not following important design and construction considerations and then ensuring proper construction and protection during and following construction. As with any asset, future maintenance is an important consideration and there are different options that the City can choose for maintenance of the porous concrete sidewalks. Porous concrete sidewalks are a new material and the design and construction considerations are being refined as the engineering and construction community gains more experience. The use of porous concrete sidewalks reduces, and in some cases may eliminate the need for conventional storm water flow control facilities and other drainage infrastructure and reduce overall project costs. Moss growth is more of an issue in wet and shady areas. Due to the wet weather environment in the Pacific Northwest, moss is a problem on any surface, including impermeable concrete sidewalks.

New development projects are required to construct frontage improvements including new sidewalks. City Transportation projects also require the construction of new sidewalks. The construction of sidewalks adds to the overall project's requirement for flow control mitigation and the need for flow control facilities and conveyance systems. These stormwater drainage facilities have construction, maintenance and replacement costs, and require land for construction. For linear transportation projects, flow control facilities require additional land, easements, or right-of-way due to the lack of space in most existing right-of-way. The use of porous concrete sidewalks allows the sidewalk to be modeled as 50%grass and 50% impervious instead of 100% impervious, potentially reducing the need for or size of a flow control facility or conveyance systems, which reduces costs. The use of porous concrete sidewalks is a way of reducing runoff from new construction, which reduces the need for conventional stormwater infrastructure, reduces downstream flooding, recharges aquifers that maintains base flows in streams, and improves water quality and fish habitat. As specified by the 2007-2013 NPDES Permit, the City's drainage code requires the implementation of flow control Best Management Practices (BMPs) for a portion of the site being developed. Porous concrete sidewalks are an option that is available for use as a flow control BMP. The adopted Surface Water Design Manual requires an adjustment if the porous concrete sidewalk is proposed to be placed in the City right-of-way by a private development. A Mr.Zimmerman Page 2 of 9 January 23,2014 There have been two City projects where porous concrete sidewalks have already been constructed. These projects are the NE 3rd/4th Corridor Transportation Improvement project and the Lake Washington Blvd Storm and Water System Improvement (Hawks Landing) project. The Surface Water Utility is currently working on two Washington State Department of Ecology (Ecology) grant funded projects to install pervious concrete sidewalks on Harrington Ave NE (Harrington Ave NE Green Connections project). These projects were part of the Sunset Area Planned Action EIS that was approved by Council. The City was successful in obtaining the Ecology grant funds because the projects retrofitted stormwater runoff from the street to provide water quality and reduce runoff by the use of porous concrete sidewalks. In addition, the Renton Housing Authority (RHA) has been approved to install pervious concrete sidewalks as part of the Kirkland Townhomes project, but they are responsible for the maintenance of the sidewalk. The development and engineering community is interested in using pervious concrete sidewalks and pavements on future projects to reduce the storm water runoff impacts from their projects. This allows them to reduce conventional stormwater facilities for control of runoff and the associated cost. By reducing the space needed for flow control and water quality treatment facilities, it allows new development to create more buildable areas on their property. This results in increased property value, which is a benefit to the developer, but also to the City through increased property tax revenues. The new 2014-2017 Phase II NPDES Permit requires jurisdictions to adopt the Ecology 2012 Stormwater Management Manual for Western Washington by no later than December 31, 2016. The Ecology 2012 Manual requires new on-site stormwater management requirements. There are specific requirements for BMPs implementation of all hard surfaces. Per Minimum Requirement#5 on Pages 2-30 and 2-31 of the attached pages from the Ecology Stormwater Management Manual for Western Washington (Ecology Manual), all hard surfaces in projects resulting in more than 2,000 square feet of new plus replaced hard surfaces have to be mitigated (when feasible) by full dispersion, permeable pavement, bioretention, and/or sheetflow dispersion in the order listed, with the specific requirement of permeable pavement to be used when pavement is proposed. The applicant/engineer will need to demonstrate that a certain on-site stormwater BMP is not feasible in order to move down the list of on-site BMP implementation. The Ecology Manual provides feasibility criteria for all on-site BMPs including permeable pavements (BMP T5.15) on Page 5-16 attached for Permeable Pavement (porous concrete) feasibility criteria. An alternative for compliance with the on-site stormwater management requirement is to construct a facility designed per the Low Impact Development Performance Standard. See attached Page 2-30 for the Low Impact Development Performance Standard. Because stormwater mitigation in City right-of-way is space limited and may require land acquisition,the use of porous concrete sidewalk may be (when feasible) the best alternative for BMP implementation on right-of-way projects due to the lack of space for the facility and the cost for land acquisition.

They have also found that spraying the porous concrete with Scotts Roundup® controls moss, but they do not use it for environmental reasons and concerns from the public. There are more environmentally friendly sprays that could also be used, such as oregano oil, but there is still the public perception problem with spraying in their community. The city of Puyallup allows porous concrete sidewalks in their right-of-way and currently has two private development projects with porous concrete sidewalks with two other projects in the permit review process. Puyallup City Code requires the abutting property owner to maintain the sidewalks, standard or porous, in the city. However, they also do not have a history of requiring property owners to repair sidewalks at their own expense. They have not had any problems with moss growth on the porous concrete sidewalks, but they are relatively new sidewalks. The city of Puyallup has completed a project that included both pervious concrete and permeable paver sidewalks (8th Ave NW LID Retrofit project). The abutting property owner is responsible for the sidewalk maintenance, even though it was constructed as part of a city project. The city of Puyallup has recently H:\File Sys\SWA-Surface Water Section Administration\SWA 03-Correspondence-General\Maintenance\Porous Concrete Sidewalk\PCS memo_to_greg.doc\HCBtp Mr.Zimmerman Page 8 of 9 January 23,2014 paved two streets with porous asphalt and will be constructing at least two other projects with pervious concrete sidewalks, as well as porous pavement travel lanes. Maintenance Responsibility: As with other types of street improvements, adjacent property owners are responsible for maintaining sidewalks, driveways and parking pads as well as landscaping in the street right-of-way, per our City Code. We can determine that the adjacent property owner is also responsible for the maintenance of porous concrete sidewalks, as currently required by City Code. To permit the placement of porous concrete sidewalks in the right-of-way, the City's Drainage Code requires a code modification similar to the King County road variance requirement. The property owners maintenance of the porous concrete sidewalk can be made a condition of the code modification and recorded in a covenant against the property. This is similar to how we allowed the Renton Housing Authority to construct porous concrete sidewalks in City right-of-way as part of the Kirkland Townhomes project. This would be consistent with our City Code requirements for impermeable sidewalks and with what other jurisdictions are doing. For City projects that use porous concrete sidewalks or use permeable pavements, the Department/Division/Section that constructs the project could be responsible for funding the maintenance of the porous concrete sidewalk or permeable pavement, but the maintenance could be performed by a designated City section. Another option would be for the City to accept the maintenance of the porous concrete sidewalks that are constructed in the public right-of-way and assign the maintenance of the porous concrete sidewalks to the Surface Water Utility and the cost for the maintenance program funded by the Surface Water Utility rates. The work could be done with in-house resources or contracted out to the private sector. This option would require the establishment of a budget that would need Council approval and require a Utility rate increase. Conclusion: The construction of porous concrete sidewalks in City right-of-way currently has mostly been done or is being proposed to be done as part of City projects, except the Renton Housing Authority Kirkland Townhomes project. The City will face increasing requests to allow its use and the use of permeable pavements for roadways in the future by developers and their engineers due to the benefits in reducing costs and the desire to build "green" projects that the public supports. The new 2014-2019 NPDES Permit will require the City to adopt standards that require more use of porous concrete sidewalks and permeable pavements after December 31, 2016. H:\File Sys\SWA-Surface Water Section Administration\SWA 03-Correspondence-General\Maintenance\Porous Concrete Sidewalk\PCS memo_to_greg.doc\HCBtp Mr.Zimmerman Page 9 of 9 January 23,2014 The most important method for avoiding the growth of moss on porous concrete sidewalks is following the design, construction, and maintenance requirements to establish and maintain the porosity of the porous concrete sidewalks to be free draining. Use of more sand in the concrete mix would result in less porosity, which may create conditions that are more conducive to moss growth. There are many examples of porous concrete sidewalks with moss growth, but this may be the result of not following important design and construction considerations and then ensuring proper construction and protection during and following construction. As with any asset, future maintenance is an important consideration and there are different options that the City can choose for maintenance of the porous concrete sidewalks. Porous concrete sidewalks are a new material and the design and construction considerations are being refined as the engineering and construction community gains more experience. The use of porous concrete sidewalks reduces, and in some cases may eliminate the need for conventional storm water flow control facilities and other drainage infrastructure and reduce overall project costs. Moss growth is more of an issue in wet and shady areas. Due to the wet weather environment in the Pacific Northwest, moss is a problem on any surface, including impermeable concrete sidewalks.

The Sunset Area Surface Water Master Plan identifies areas where green street improvements could be made at locations that fit with existing U and planned future land use in the area and the construction of a sub-regional storm water infiltration facility. The green streets stormwater improvements consist of Lam/-1Ad ae constructing rain gardens and orous concrete sidewalks primarily along Harrington Avenue NE. The sub-regional stormwater infiltration facility consists of constructing an infiltration/flow control facility with a rain garden storm water facility providing water quality treatment. These improvements will retrofit existing storm systems in the area to reduce stormwater quantity and improve the quality of stormwater runoff specifically reduction in total suspended solids and fecal coliform loading, from the existing and future land use within the Sunset Community Plan Area which discharge to Johns Creek and Lake Washington. The purpose of this project is to collect data on subsurface conditions and soil infiltration capacity and update existing hydrologic and hydraulic analysis to refine sizing and design requirements of the green streets and sub-regional stormwater infiltration facility improvement. This phase of work will also include development of a conceptual layout and details of the LID facilities.

However, if state funds are appropriated by July 1, 2013,there will be no impact on the above-captioned agreement. Specifically, this letter is a contingent notice of termination of the above-captioned agreement with an effective date beginning July 1, 2013, and a proposal to amend the agreement to provide for suspension in lieu of termination. This matter requires your immediate attention and prompt action. Thank you in advance for working quickly to address this situation and manage our agreement documents at this difficult time in fiscal planning. As of the date of this letter, the Washington State Legislature has not yet enacted a state operating budget to appropriate funds to state agencies for the upcoming biennium. In the unlikely event that the state legislature does not enact a state operating budget before the beginning of the new fiscal biennium on July 1, 2013, state agencies operating on appropriations will no longer be authorized to incur expenses, such as through your above-captioned agreement .with the Department. Under the Washington State Constitution,Article VIII, Section 4, and RCW 43.88.130, the state cannot expend or agreement to expend money or incur financial obligations that are not authorized through appropriations. The appropriations set forth in the state's current operating budget end on June 30, 2013. As required by these circumstances,the Department hereby gives this contingent notice of termination to the above-captioned agreement effective July 1, 2013, in the event that a state operating budget has not been enacted at that time. This termination notice is thus contingent upon the potential unavailability of state funds. If appropriations are enacted to fund the Department effective July 1, 2013, no termination shall go into effect and the agreement shall continue unimpeded. RENTON CITY OF-G1200544 Page 2 June 20,2013 The Department would prefer to suspend rather than terminate the agreement in order to facilitate resumption of the agreement upon enactment of state funds. In order to affect a suspension in lieu of termination,please review the attached agreement amendment entitled Suspension of Performance and Resumption of Performance. If this arrangement is acceptable, please sign, scan, and send this agreement amendment using one method below as soon as possible,preferably within five days. By Email: . amendments@ecy.wa.gov OR By Fax: 360-407-7153 This amendment will allow this agreement to survive a disruption of state funds and avoid the need to establish new agreements after the subsequent authorization of funds. Finally, if no operating budget is enacted by July 1, 2013, the Department directs you at that time to cease or refrain from any activity that incurs expense to the state under this agreement. Please note that sub-contracts that you have awarded as part of the work under this agreement are also subject to the effect of this contingent termination or suspension in lieu of termination. We expect you to notify your sub-contractors of this situation and instruct them to be prepared to suspend work effective July 1, 2013, if no state operating budget has been enacted in order for you to avoid incurring costs that will not be eligible for reimbursement. We understand that this uncertainty is concerning to our partners and we appreciate your patience in the coming weeks as we all await enactment of a state operating budget. In the meantime,we appreciate your prompt action in processing this agreement amendment. During this time, please direct all questions to your Ecology Project Manager, who will act as your point of contact regarding this issue.
